Kodak XD plates

[SérgioMateus]

Hello!

I'm having problems with the XD Thermal plates. some of the plates apears a little bit 'foggy' at the end of the plates (not in the leading or trailing edge, on the sides).
The kodak send an engeneer to solve the problem but the only thing that he told was that i was runing with the wrong processor parameters.
it was 1300milimiters/min and 23,5celsius degrees, he told me to run 1500milimiters/min and 21celsuis degreees.
this week i notice that the chemistry is getting weaker easily...i ask him about the replenish values and he told me to keep the same....150ml/square meter.


i realy think that the problem are in the plates and i should never acept the NEW processor parameters.

can the XD plate users tell me the parameters that you run on the processor...speed & temp...?

thank you all

What is your plate setter? Processor?

foggy as in the plate going blind?, i.e. image/dot worn off? is that after a run or prior to going on the press?

To answer you question first Gordo, we have imaged the plate vertically as opposed to horizontally, no visible marks post processing under a 200x lupe, after 48.000 copies lines appear.

And to answer your question Alois, the lines are uniform in width but appear at random intervals on the plate and there is no corresponding piling/build up on the blanket or debris in the forme rollers etc.

We have send a sample via Kodak NZ (i must mention their service has been outstanding) to their plant in China.

As an aside changing to an new batch this morning for one of our presses has produced no "tramlines" so far, the press is up to 430.000 good copies.....

Hi,

Can we go back to pre-press room? What kind of plate setter are you using? What is your processor? How do you load the plates? Have you ever tried to image the plates (at least 4colors for high run lengths) with another Plate setter and then print them using your press machines?

No problem?
Next image the plates with another plate setter and use your own processor.
No problem?
Image with your plate setter and use another processor.
No problem?
Well then your problem is Rip or Work flow. You do not need me to continue with the Rip system. If all your systems are ok. The Problem is your plates.

Summery: Get 4 Plates of same brand from somebody else, Image and Print them with your Press Machine for High run lengths. This will tell you if your plates are ok or not.

Hope this will help.

Standard SOP (Standard Operating Procedure) is as follows, but keep in mind that some adjustments are normal based on your individual circumstances - high/low volume use, ambient temperature, CTP device, processor type and condition, etc. Your plate support person probably has reasons to deviate in your case, but it's always good to check.

Processing speed: 1300-1500mm/min (21-25 sec. dwell time)
Temperature: 23C
Replenishment: 90-110ml/m2
Anti-Ox: 4 liters/24h (because you have a huge processor - it's less for smaller ones)
